Amador County, CA Swimming Pools & Spas: Hot Tub Rules (2026)

A private residential hot tub or spa in the unincorporated county follows the California Building Codes adopted by reference in Amador County Code Chapter 15.04. The code definition of a 'swimming pool' expressly includes hot tubs and portable/non-portable spas, so a spa holding 18 inches or more of water is regulated like a pool. Spas and hot tubs - whether permanent or portable - are governed by the California Electrical Code and California Plumbing Code, so the electrical hookup, bonding and any plumbing require permits. When a building permit is issued for a residential spa, the California Swimming Pool Safety Act (Health & Safety Code 115922) requires at least two approved drowning-prevention features; for spas, an ASTM F1346 listed safety cover with a lockable latch is a common compliance path and counts as one of the approved features. Many factory-made portable spas with a lockable hard cover satisfy the cover requirement, but local electrical permitting still applies. PUBLIC and commercial spas (apartments, HOAs, hotels, clubs) are a separate matter handled by Amador County Environmental Health under California Code of Regulations Title 22, including water-quality logs and anti-entrapment device filings - those rules do not apply to a private home spa. Confirm exact permit needs with the Building Department, since they depend on the spa's depth, location and electrical service.
